Title: Electric lighter for pipes, cigars and cigarettes specially for motor-cars
IPC: F23Q7/00
Filed: 1929-01-25
Abstract: 304,790. Manger, K. Jan. 27, 1928, [Convention date]. Lighting pipes, cigars, and the like by electric devices. - An igniter comprises a sheet-metal casing 1 secured, for example, to the side or switchboard of a motor car and a hollow plug 2 removable from the casing 1 and fitted with a spindle 10 carrying an insulating cup 14 from which projects a flat spiral wire 3 which is raised to incandescence when the spindle is pressed downwards against the resistance of a spring 12 so as to cause a metal cap 15 surrounding the cup 14 to contact with a tongue 6 carried by one of two terminals 5 connected to the car battery. The current passes from the cap 15 through the wire 3 to a metal disc 17 which is insulated from the cap 15 by a disc 16 and then through the plug 2 to the casing 1 which is electrically connected to the other terminal 5. A coloured glass knob arranged in the front of the casing 1 at the height of the tongue 6 shows when the wire 3 has reached incandescence. When lighting a pipe the spindle is maintained in the depressed position after the plug has been removed from the casing 1 so that the incandescent body can be inserted in the pipe bowl.

Title: Alarm system
IPC: G08B13/04
Filed: 1972-01-20
Abstract: 1415498 Intruder alarms SECURITAS ALARM Ltd 22 Jan 1973 [20 Jan 1972] 2719/72 Heading G4N An alarm system for detecting breakage of a sheet of glass includes a pair of detectors for detecting two types of vibration when glass is broken, and an alarm which is actuated only when both detectors produce an output. The first detector is a microphone 42 coupled via a frequency selective amplifier 43 and a detector 44 ... 47 to a normally conductive transistor TR5. The second detector is a vibration sensitive switch 15 which is coupled via a trigger circuit TR6, TR7 of which transistor TR7 is normally conducting. Transistor TR8 is thus normally cut off, and TR9 normally conducting to energize relay R11 which hold contacts 35 closed. A signal at either detector will cause its associated transistor TR5 or TR7 to cut-off, but only if both are cut-off can TR8 become conductive. When this occurs, TR9 is cut-off, relay R11 releases closing alarm contacts 41, and contacts 35 open to prevent the relay reenergizing until reset button 50 is operated. In order to adjust the microphone sensitivity control RV1, button L1 is operated giving a simulated signal in the other channel. The system includes a number of vibration sensitive switches 15, and a further microphone may be connected to input 2. The alarm will also be initiated if the units are tampered with, tamper, switches 13, 17 cutting off the supply to the relay R11.

Abstract: 911,689. Horizontal coke ovens. SIMONCARVES Ltd. Jan. 25, 1961 [March 28, 1960], No. 2870/61. Classes 51 (1) and 51 (2). In a compound CoppÚe type coke oven, each heating flue has a passage for supplying lean gas and a passage for supplying air entering the heating flue through a common opening in the floor of the flue, and a conduit partly overlying the common opening and leading mixed gas and air to a point above the bottom of the flue, and a rich gas inlet horizontally offset from the air and gas inlet. In a regenerative, hairpin flued oven the passages from the gas and air heating regenerators, separated by a partition 41, open into a common T-shaped inlet 62 in the bottom of the flue. A conduit 66 supported by bricks 63, 65 limiting the stem of the T-opening overlies the stem part 67 only of the inlet. Sliding bricks 74, 76 control the size of the inlet formed by the arms 70 of the T-opening, and a sliding brick 78 controls the top outlet of the conduit 66. A divider 80 separates the gas and air flowing into the conduit. During lean gas operation, gas and air mix in the arm part 70 of the inlet to burn at the bottom of the flue, while the gas and air entering the conduit 66 mix above the partition 80 to burn in the conduit 66 and flow into the flue. The thin walls of the conduit radiate heat to the lower part of the flue to equalize the heating throughout the height of the oven. During rich gas heating, combustion air is supplied to the flues through both passages, part forming a stream of air from the bottom of the flue parallel to and horizontally spaced from a vertical stream of rich gas from the nozzle 56, and part forms a second parallel stream of air entering the flue at the top of the conduit 66 so that even heating can be obtained over the height of the oven. Specification 911,688 is referred to.

Abstract: 1,063,761. Yarn tensioning apparatus. SOCIETE RHODIACETA. Jan. 27, 1965 [Feb. 12, 1964], No. 3668/65. Heading DID. A device for maintaining a constant tension in a yarn comprises a cylinder rotated at a peripheral speed greater than the rate at which the yarn travels and in the same direction, means to guide the yarn to travel through at least one arc in contact with the cylinder and including at least two yarn guides mounted so as to move when the tension rises so as to increase the length of at least one of the arcs, and means tending to move the guides in a direction which decreases the length of the arc. Yarn 6 passes over a driven roller (1), guides (2<SP>1</SP>, 2) and over the roller again. Roller 1 is driven faster than the yarn travels and the guides (2, 2<SP>1</SP>) which may be pulleys are on arms (3, 3<SP>1</SP>) which can rock about pivots (4, 4<SP>1</SP>) against the pull of a spring (5) when the tension rises, to increase the extent which the yarn embraces the roller. The value of the working tension may be set by varying the force of the spring, or by changing the roller for one with a different surface. The spring may be replaced by a counterweight, a pneumatic device or an electromagnetic device. In another form the yarn enters and leaves the device over fixed guides arranged respectively before and after the guides (2, 2<SP>1</SP>), the yarn in this case making one arc of contact with the roller.
